Description

Technical Field

[0001] The utility model belongs to the technical field of automotive instrument, and particularly relates to a lightweight automotive instrument panel crossbeam assembly. Background Art

[0002] The instrument panel crossbeam is one of the important safety components of an automobile. The steering column, instrument assembly, PAB, etc. are fixed on the instrument panel crossbeam. On the one hand, when a vehicle collides, if the strength of the instrument panel crossbeam is insufficient, the PAB cannot explode normally, and the airbag cannot protect the driver well, or if the X-direction stiffness is excessive, it is easy to injure the driver. On the other hand, users can directly feel its performance advantages and disadvantages by touching with their fingers, and users evaluate the product quality by perceiving the vibration level of the steering system. The key factors affecting the performance of the steering system include the stiffness of the steering column itself, the stiffness of the CCB, and the stiffness of the body connection. Therefore, the performance design of the instrument panel crossbeam is crucial.

[0003] For example, the Chinese patent with the publication number CN 217100191 U discloses an automotive instrument panel crossbeam structure, including a beam frame. Connection and fixing components connected to the vehicle body are provided at both ends of the beam frame. A steering column mounting bracket and a middle channel support bracket are provided on the beam frame. The upper ends of the left middle channel support bracket and the right middle channel support bracket are welded to the beam frame, and the lower ends are respectively connected to the left middle channel connection bracket and the right middle channel connection bracket. Bolt holes connected to the vehicle body middle channel are provided on the left middle channel connection bracket and the right middle channel connection bracket.

[0004] The crossbeam structure disclosed by this technical solution is simple, can meet the structural performance requirements, and is light in weight. However, in this technical solution, the connection relationship between the connecting member and the beam frame is welding, and heat treatment will cause the strength of the beam frame to decrease. Therefore, a thicker beam frame is required, or a bolt connection device is used. Multiple bolt connections will increase the weight of the device. Summary of the Utility Model
